Abstract

The invention discloses a multilayer cholesteric liquid crystal film and a preparation method thereof. The multilayer cholesteric liquid crystal film includes a first base layer and a second base layer which are arranged in an opposite manner, a red cholesterin liquid crystal layer, a green cholesterin liquid crystal layer and blue cholesterin liquid crystal layer, wherein the red cholesterin liquid crystal layer, the green cholesterin liquid crystal layer and the blue cholesterin liquid crystal layer are arranged between the first base layer and the second base layer successively; the blue cholesterin liquid crystal layer includes cholesterin liquid crystals which can reflect the blue wave band light, and first chiral materials; the green cholesterin liquid crystal layer includes cholesterin liquid crystals which can reflect the green wave band light and second chiral materials; and the red cholesterin liquid crystal layer includes cholesterin liquid crystals which can reflect the redwave band light and third chiral materials. The multilayer cholesteric liquid crystal film can replace a multilayer reflective film to use, and can solve the problem that a current multilayer reflective film is high in price, complicated in structure and limited to use.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a multilayer cholesteric liquid crystal film and a preparation method thereof. Background technique [0002] Liquid crystal display is currently the most widely used display in the market. Since it is not a self-luminous display itself, it needs to rely on backlight and a variety of optical films such as polarizers, diffusion films or brightness enhancement films to achieve high brightness. High-quality, high-definition and high-brightness optical characteristics, and in order to obtain higher brightness, wider viewing angles, and wider color gamut, it is usually achieved by using a multi-layer brightness enhancement film. Compared with traditional polarizers, the brightness enhancement film can increase the brightness by about 60% and has the polarization effect of traditional polarizers. At present, the best and most widely used is the multi-level birefringence ...
